Smart Vision offer a free copy of SPSS Statistics that will give you access to the software for a trial period of two weeks. This video will talk you through how to download and install the software before providing a series of examples of procedures that you might want to try out yourself in order to explore SPSS. You should be aware that the trial software includes all of the SPSS Statistics optional add on modules and you can find out more about these modules and see a two minute overview of each one elsewhere on this site.
Once installed you need to activate the trial license. This is done by entering your email address into the prompt box when you first open the software. If you receive an error message, this is normally due to your internet security blocking connection to the IBM Licensing Servers. You will need to allow the software access to the internet. This means changing your internet security and firewall settings and therefore you will probably need to contact your IT Department.
Other things to check are that you have full administration rights during installation of the software and that SPSS Statistics has not been installed on this machine previously.
